refactor(ts): Convert internal window dependencies to ES modules

Phase 1 of ESBuild migration: Convert 193+ internal window reads
to proper ES module imports across consumer modules.

Replaced window global pattern with direct function imports:
- (window as any).showToast → import { showToast } → showToast(msg, "type")
- (window as any).api.post → import { apiPost } → apiPost(url, data)
- (window as any).dom.getElementById → import { getElementById }

Modules migrated:
- admin.ts: Convert 14 showToast window reads
- analytics.ts: Add ES export (no window reads)
- conflicts.ts: Convert 6 showToast window reads
- custom-section-builder.ts: Convert api.post reads, add ES exports
- dashboard.ts: Convert 10 window reads (api, showToast)
- device-management.ts: Convert 4 showToast window reads, add Alpine registration
- linking.ts: Convert showToast window reads
- queue.ts: Convert 8 showToast window reads

Additionally added Alpine.js registration for templates:
- device-management.ts: Register copyToClipboard, regenerateDeviceToken

Benefits:
- Type-safe imports with build-time validation
- No runtime checks needed (ES modules guarantee existence)
- Clear dependency chains via explicit imports
- Eliminates 193+ window global reads

Pattern now: Import at top, direct function calls, Alpine registration
at bottom for template access.

Migration progress: Phase 1 complete
Next: Phase 2 (Alpine registration for remaining modules)
